Contributor:  Aaron Lessen, MD Educational Pearls: Facial nerve palsy (Bell’s palsy) can occur in pediatric patients with Lyme disease, viral infection, or even leukemia One trial sought out to find if steroids and acyclovir would benefit pediatric patients with facial nerve palsy However, during screening process, around 1% of enrollees had leukemia (5 of the 644 patients)  This is important as steroids can partially treat the leukemia thereby prolonging diagnosis and put the patient at risk for tumor lysis syndrome References Babl FE, Kochar A, Osborn M, et al. Risk of Leukemia in Children With Peripheral Facial Palsy.
